Baochen Qiang 7e2368a217 dma-debug: don't enforce dma mapping check on noncoherent allocations ...

As discussed in [1], there is no need to enforce dma mapping check on
noncoherent allocations, a simple test on the returned CPU address is
good enough.

Add a new pair of debug helpers and use them for noncoherent alloc/free
to fix this issue.
